BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described further, by way of a non-limiting example
only, with reference to the accompanying drawings wherein: . figures 3 to 5 are cross-sectional side views of a closure for the waste
invention as shown in more detail in figures 4 and 5; figure 4 is an exploded cross-sectional side view of a waste assembly according to a preferred embodiment of the invention; and figure 5 is an assembled cross-sectional side view of the waste assembly of figure 4.
DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
Referring to figures 1 to 3, a closure for a waste outlet assembly of a bath, sink, basin and the like, is generally designated by reference numeral 10. The closure 10 is particularly suitable for use with a weir generally designated by reference numeral 12 in figures 4 and 5.
The closure 10 comprises a relatively flat flexible rubber disc 14 having a sealing surface 16 for sealingly engaging the weir 12. The closure further includes attaching means for attaching the closure 10 to the weir 12, the
attaching means comprising a magnet 18 disposed in a cylindrical flange 20
extending from the under-side of the disc 14. The closure 10 further includes an annular frusto-conical flange 22 extending from the same side of the disc 14 than the cylindrical flange 20.
The magnet 18 is provided with a plurality of circumferentially extending outer
groove formations T871 and the conical~flange 2ϋ~rs — rovided— wrttr circumferentially extending internal groove formations 20.1 for mating with the
external groove formations 18.1 of the magnet 18. In use, the position of the magnet 18 relative to the cylindrical flange 20 is thus adjustable by pressing the magnet 18 inwards, as indicated by arrow A in figures 1 and 2.
Referring to figures 4 and 5, the weir 12 comprises a body 24 having a tubular portion 26 of which an outlet end is closed by a weir member 28 and an inlet end of which is provided with a circumferentially extending flange 30. A plurality of outlet holes 32 are provided in the weir member 28. The weir member 28 is further provided with a centrally located aperture 34 and a hole 36 for receiving a screw 38 for connecting the weir 12 to a waste outlet assembly (not shown).
The screw 38 is of a plastics material and comprises an elongate threaded shaft 40, a head 42 and a locating ridge formation 44 disposed on the shaft 40, for engaging the periphery of the hole 36 on the outlet side, to locate the head 42 in the aperture 34. The weir member 12 further includes a magnetisable member
in the form of a metal clip 46 which attaches to the head 42 and which is trapped in the aperture 34 when the head 42 is located in the aperture 34.
In use, the position of the magnet 18 is adjusted by moving the magnet 18 relative to the tubular flange 20 to the optimum position such that the magnet 18
abuts the metal clip 46 when the closure 10 is disposed in the weir member 12.
It will be appreciated that variations in detail are possible with a waste assembly and components thereof according to the invention without departing from the scope of the appended claims. For example, in an alternative arrangement, the head of the screw defines a circumferentially extending groove formation and the metal clip defines a complementary ridge formation for mating therewith in clip-on fashion. Further for example, the metal clip can be glued to the weir member. In such arrangement, conventional waste outlet assemblies can be adapted to receive the closure 10, by gluing the metal clip to the weir member, and adjusting the magnet to a suitable depth.
